Embodiment Construction
[0029] Vapor compression refrigeration cycle device of the present invention such as figure 2 As shown, the outlet of the compressor 22 is connected to the inlet of the booster pump 24 after being connected in parallel with the outlet of the restrictor 25 . After the inlet of the expansion motor 26 is connected in parallel with the inlet of the restrictor 25, it is connected to the outlet of the condenser 23. The inlet of the evaporator 27 is connected to the outlet of the expansion motor 26 , and the outlet of the evaporator 27 is connected to the inlet of the compressor 22 . The outlet of the booster pump 24 is connected to the inlet of the condenser 23 . The expansion motor 26 is coaxially connected to the booster pump 24 .
[0030] In the refrigeration cycle of the present invention, the isentropic expansion of the expansion motor 26 greatly reduces the enthalpy of the working fluid entering the condenser; the use of the booster pump 24 makes the operating pressure diff...
